Lattice QCD on Non-Orientable Manifolds
Simon Mages, Balint C. Toth, Szabolcs Borsanyi +3
A common problem in lattice QCD simulations on the torus is the extremely long autocorrelation time of the topological charge, when one approaches the continuum limit. The reason i…
Static quark-antiquark pair free energy and screening masses: continuum results at the QCD physical point
Szabolcs Borsanyi, Zoltan Fodor, Sandor D. Katz +3
We study the correlators of Polyakov loops, and the corresponding gauge invariant free energy of a static quark-antiquark pair in 2+1 flavor QCD at finite temperature. Our simulati…
QCD thermodynamics with continuum extrapolated dynamical overlap fermions
Sz. Borsanyi, Z. Fodor S. D. Katz S. Krieg, T. Lippert +4
We study the finite temperature transition in QCD with two flavors of dynamical fermions at a pseudoscalar pion mass of about 350 MeV. We use lattices with temporal extent of …
Lattice computation of the nucleon scalar quark contents at the physical point
S. Durr, Z. Fodor, C. Hoelbling +10
We present a QCD calculation of the , and scalar quark contents of nucleons based on lattice ensembles with dynamical sea quarks, lattice spacings d…
Axion cosmology, lattice QCD and the dilute instanton gas
S. Borsanyi, M. Dierigl, Z. Fodor +6
Axions are one of the most attractive dark matter candidates. The evolution of their number density in the early universe can be determined by calculating the topological susceptib…
Fluctuations and correlations in high temperature QCD
R. Bellwied, S. Borsanyi, Z. Fodor +4
We calculate second- and fourth-order cumulants of conserved charges in a temperature range stretching from the QCD transition region towards the realm of (resummed) perturbation t…
